    摘要： There are provided a pressure-sensitive adhesive composition containing stably dispersed metal-based fine particles, having further reinforced mechanical properties, and being capable of forming a pressure-sensitive adhesive layer with excellent refractive index and excellent adhesive strength, and a pressure-sensitive adhesive sheet produced therewith. A pressure-sensitive adhesive composition is prepared which includes as a monomer component 100 parts by weight of a (meth)acrylic polymer including 50% by weight or more of a (meth)acrylate represented by the formula CH 2 =C(R 1 )COOR 2 , wherein R 1 represents hydrogen or a methyl group, and R 2 represents a substituted or unsubstituted alkyl group of 1 to 20 carbon atoms, having a weight average molecular weight of 500,000 to 3,000,000 as determined by gel permeation chromatography, and being substantially free of an acid component; 5 to 100 parts by weight of a low-molecular-weight aromatic polymer having a weight average molecular weight of 500 to 4,000 as determined by gel permeation chromatography; and 5 to 100 parts by weight of metal-based fine particles having an average particle size of 5 to 100 nm.

    摘要： An object of the invention is to provide a pressure-sensitive adhesive optical film-peeling method capable of easily detaching the pressure-sensitive adhesive optical film from a glass substrate with no damage to the glass substrate or no adhesive deposit on the glass substrate, and to provide a pressure-sensitive adhesive optical film suitable for use in such a peeling method. The invention is directed to a method for peeling a pressure-sensitive adhesive optical film from an optical film-carrying glass substrate including a glass substrate and the pressure-sensitive adhesive optical film bonded thereto, which includes: exposing the optical film-carrying glass substrate to an environment at a temperature of 40 °C to 98 °C and a relative humidity of 60 % to 99 % for three minutes or more; and then peeling the pressure-sensitive adhesive optical film from the glass substrate under the environment.
